The "dots" in a electron dot structure (Lewis Dot) represent the following: Valence electrons, the electrons that are in a noble gas.
Valence electrons, all the electrons that surround the nucleus of an atom
The group numbers 1A thru 8A
Valence electrons, the outer most electrons used in bonding

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

idk i’m struggling too

did anyone actually do this? like if anyone has submitted this i rly need .

answer: they produce more slow than unicellular organisms.
